[PATCHv1,0/5] ASoC: da7213: support for usage with simple-card

Hi,

This extends the da7213 driver to be used with simple-audio-card in
combination with a fixed clock. Here is a snippet of the downstream
board's DT, that is supposed to be supported by this patchset.

/ {
        sound {
                compatible = "simple-audio-card";
                simple-audio-card,name = "audio-card";
                simple-audio-card,format = "i2s";
                simple-audio-card,bitclock-master = <&dailink_master>;
                simple-audio-card,frame-master = <&dailink_master>;
                
                simple-audio-card,widgets = "Speaker", "Ext Spk";   
                simple-audio-card,audio-routing = "Ext Spk", "LINE";
                
                simple-audio-card,cpu {
                        sound-dai = <&ssi1>;
                };

                dailink_master: simple-audio-card,codec {
                        sound-dai = <&codec>;
                };
        };

        clk_ext_audio_codec: clock-codec {
                compatible = "fixed-clock";
                #clock-cells = <0>;
                clock-frequency = <12288000>;
        };
};

&i2c1 {
        codec: audio-codec@1a {
                compatible = "dlg,da7212";
                reg = <0x1a>;
                #sound-dai-cells = <0>;
                VDDA-supply = <&reg_2v5_audio>;
                VDDSP-supply = <&reg_5v0_audio>;
                VDDMIC-supply = <&reg_3v3_audio>;
                VDDIO-supply = <&reg_3v3_audio>;
                clocks = <&clk_ext_audio_codec>;
                clock-names = "mclk";
        };
};
